Answer
The length of each side of the square = 19 units.
Step-by-step explanation
The area of a square is given as
Area = L²
where
L = length of a side of the square (since all the sides have the same length)
For this question,
Area = 361 square units
Length = L = ?
361 = L²
L² = 361
Take the square root of both sides
√L² = √361
L = 19 units.
